    Droughts in Chile: Impacts, Monitoring, and Adaptation (Management) Policies
    (Springer, 2025) Rivera Bravo, Daniela Pilar; Donoso H., Guillermo; Gironás León, Jorge Alfredo; Núñez Grahmann, Marialina I.; Morandé, Felipe G.; Meza, Francisco Javier; Fernández, Francisco J.; Vásquez-Lavín, Felipe; Díaz, José A.; Montecinos, Mauricio; Rivera, Daniela; Donoso, Guillermo
    The case of Chile is illustrative of a transition from command and control to market-based management policies, where economic incentives play a significant role in water management. This book deals with drought policy in Chile and other countries. It offers a detailed examination of drought management and policies. It describes, analyzes and evaluates the performance of drought policies, laws and institutions, identifies the main challenges that Chile faces and derives lessons learnt. Expert contributors discuss such topics as Chile’s drought water policy, and the reasoning which explains present challenges.

    Factors that affect fruit consumption in schools of the Metropolitan Region (Chile): The case of two schools in the district of Lo Prado
    (2012) Beaujanot, Andre; Donoso, Guillermo; del Valle, Andrea
    A. Beaujanot, G. Donoso, and A. del Valle. 2012. Factors that affect fruit consumption in schools of the Metropolitan Region (Chile): The case of two schools in the district of Lo Prado. Cien. Inv. Agr. 39(1): 19-35. This research identifies the influence of environmental, social and consumer habits on decision making of children's fruit consumption. The characteristics that influence children's fruit consumption in school and their willingness to change these consumption behaviors are also studied. The study is performed on 5th and 8th grade students who attend public and private elementary schools in the municipality of Lo Prado, Santiago. The level of fruit consumption significantly depends on the family and school support that children receive. Statements such as: "Fruits are good for my health" and "Fruits are rich in vitamins" are very important for parents and children who attend private and public schools. From a strategic point of view, this research concludes that a more proactive and consistent approach is needed from parents and school communities to encourage fruit consumption among children. This approach results in either maintaining or improving children's fruit consumption as they grow older. Also, the actions of parents and schools towards the preparation of desserts using fruits are proven to be an effective way to increase fruit consumption.

    Introduction, Objectives, and Scope
    (SPRINGER INTERNATIONAL PUBLISHING AG, 2018) Donoso, Guillermo
    The field of water resources is interdisciplinary in nature, covering hydrological, economic, institutional, legal, environmental, social and political aspects. This diversification has led, in many cases, to partial treatment of water issues, or incomplete analysis of the various challenges at stake. This contributed book offers a selfcontained interdisciplinary overview of water policy in Chile. The book is organized in four sections.

    Management of Water Resources in Agriculture in Chile and its Challenges
    (PONTIFICIA UNIV CATOLICA CHILE, FAC AGRONOMIA INGENIERIA FORESTAL, 2021) Donoso, Guillermo
    Water is a strategic resource for agricultural development, particularly in the arid and semiarid regions of central and northern Chile. Currently, irrigated surfaces contribute between 60 and 65% of the country's agricultural GDP. Associated with Chile's economic growth, total consumptive water use has increased, which, together with population growth, urbanization, water contamination and pollution, has led to important water stress situations that are triggering a greater number of conflicts and social, economic, and environmental vulnerability. The above phenomena will be exacerbated by climate change. At present, surface water deficit covering irrigation demands exists in the central and northern regions. This deficit is projected to increase as a result of climate change, which would increase the challenges for satisfying agricultural water requirements. The objective of this article is to integrally review the key aspects of Chilean water and agricultural water management policies, considering their interphases, providing the reader with a general overview of the main features of this model, an evaluation of its effectiveness and the main challenges agricultural water management faces. Resolving the challenges of the future requires a thorough reconsideration of water management policies and institutions and how water is managed in the agricultural sector in the broader context of overall water resource management in Chile.

    Participation determinants and impact assessment of the Institute of Agricultural Development (INDAP) credit program
    (2010) Donoso, Guillermo; Melo, Oscar; Negrete, Eduardo
    G. Donoso, O. Melo, and E. Negrete. 2010. Participation determinants and impact assessment of the Institute of Agricultural Development (INDAP) credit program. Cien. Inv. Agr. 37(2): 87-99. This research estimates the impact of INDAP's Credit Program on the per hectare agricultural income of small agricultural producers. To accomplish this, a Treatment Effects Model (TEM) is employed to simultaneously estimate producer incomes and program participation functions, correcting for the potential presence of selectivity bias through the correlation between the errors of both functions. The results indicate that farmers of greater age present a higher disposition to participate in the program, but their interest decreases as their age increases. Additionally, producers who are acquainted with and evaluate the financial cost of credits as well as those producers whose income comes mainly from their land, who are landowners, present a greater family size and work greater land surfaces, present a greater disposition to participate. The results also indicate the existence of selection bias due to the nonrandom participation of farmers in the program. A negative correlation between the error terms of the per hectare agricultural income and participation function is observed. This implies that Ordinary Least Squares (OLS) underestimates the true effect of the program, because it omits the different initial situations between the treated and control group, situation corrected by the TEM estimation. In addition, the results indicate that there exists a positive and significant difference in the per hectare agricultural income between both groups in favor of the participants of the Credit Programs of INDAP, thus the Credit Program presents a positive impact on producer income levels.

    Testing the embedding effect in the valuation of lagoon recovery
    (2010) Donoso, Guillermo; Cancino, Jose; Villar, Susana
    G. Donoso H., J. Cancino, and S. Villar. 2010. Testing embedding the effect in the valuation of lagoon recovery. Cien. Inv. Agr. 37(1): 103-111. The contingent valuation method was employed to assess the benefits of recovering the Laguna Grande de San Pedro dc La Paz in Chile's Bio-Bio region and to analyze the possible existence of an embedding effect. Our results indicate that there is not a perfect part-whole valuation effect and that there is an imperfect substitution relationship between the two analyzed projects. In addition, when assessing the joint construction project of a main sewer and a recreation park on the north hillside of the lagoon, we determined that households were willing to pay an average monthly amount of $6,114 for the associated benefit of the environmental improvement. This amount would contribute $ 358,977,396 per month to the project and a total value of $4,307,728,752. Additionally, the separate valuation of the two projects resulted in an amount of $ 3,290,635,524 for the main sewer and $ 2,484,518,138 for the recreation park. The absence of part-whole valuation effect may be explained by the precautions adopted in the survey's design and application, based on the review and analysis of prior studies.
